IMPROVEMENT'VIN omen-rs Fen PAVING AND BUILDING.

The Schedulerefexted. to in these Letters Patent and making part of the same.

I, J osEPH'EvEs Horne, of the city of Philadelphia and State of Pennsylvania, have invented an Improved Paving andBuilding Cement, of which the following is a specification. l

The nature of my invention consists in the combination of resin and coal-ashes, to form a strong, dura- .{To enableothers to make and {use myinvcntion, I

will now-give'a full description tl1ereof.-

I take equal ,or-variable proportions of resin and coal-ashes. The resin I melt in a kettle or "other suitable vessel, and gradually addthereto the ashes, stirring the meltedwresin at the same time, by any convenient mode, to-insurea uniform mixture of the two substances. I Isometimes add a small quantity of grease to t-he composition, to increase its toughness, varying the proportions as circumstances may require.

I give it any desirable color by the addition of suit able coloring matter. l ,I manufacture the cement in blocks, or slabs, or

any other convenient form suitable for its particular use, or else manufacture it in bulk for transportation, to be remelted and brought into the required form when used; or the cement may be made from the crude materials at the place it is-used.

i What I claim as new, and desire to secure by Let 'ters' Patent, is-e- .The composition of resin and coal-ashes, with or without the admixture of grease, substantially as described.

Iu testimony that the above is my invention, I have hereto set my hand and afl'ixed my seal this 8th day 'of July, 1870.
